• Jürgen Klopp leads inquest following Red Star defeat• Liverpool have won only three of their last nine games

Jürgen Klopp led the inquest into Liverpool’s anaemic Champions League defeat at Red Star Belgrade as he sought to rediscover “the spark” that has disappeared from his team in recent weeks.

Klopp said Liverpool lost their mojo during the Group C reverse on Tuesday and sought answers from his players on their return to Melwood. Andy Robertson described Liverpool’s overall form as effective but lacking its usual spark, an analysis supported by the team’s best start to a Premier League season yet also a run of three wins in nine matches in all competitions.
